How does it work?
class HelloWorldWidget: GlanceAppWidget() {
@Composable
override fun Content() {
Text(text = "Hello world!")
}
}
class HelloWorldWidgetReceiver : GlanceAppWidgetReceiver() {
override val glanceAppWidget = HelloWorldWidget()
}
It uses its own Compose implementation

Glance App Widget Error example

And a similar stack trace on Logcat:

E/GlanceAppWidget: Error in Glance App Widget
java.lang.IllegalStateException: CompositionLocal LocalDensity not present at androidx.compose.ui.platform.CompositionLocalsKt.noLocalProvidedFor(CompositionLocals.kt:170)
Updating is different from Jetpack Compose

User interactions are easier to handle
Button(
text = "Home",
modifier = GlanceModifier.clickable(actionStartActivity<HomeActivity>())
)

It is also possible to create custom actions to better fit your user experience needs:

Button(
text = "Update",
modifier = GlanceModifier.clickable(actionRunCallback<UpdateAction>())
)
class UpdateAction : ActionCallback {
override suspend fun onRun(context: Context, glanceId: GlanceId, parameters: ActionParameters) {
// Update!
}
}
Make sure to test on Android 12 and below
